I'm sorry, I still can't get my head round why it only shows 'Drive1' when I type 'cd media' and when I type 'cd /media' it shows all of them!

you must have a folder called "media" in your Home folder, that contains a folder or symlink called "Drive1"(possibly a symlink we placed there so you can open/save files on Drive1 from within libreoffice ?)
